Jurors could not reach a verdict last week after seven hours of deliberation in the trial of Bierria, 32, accused of second-degree murder in connection with the 2009 death of childhood friend Soron Salter in Slidell, La., and Judge Martin Coady declared a mistrial, The (New Orleans) Times-Picayune reported Wednesday.
In the first trial, Bierria admitted choking Salter, 29, at the end of a bloody knife fight. His second trial began Tuesday.
In testimony, Amanda Vaughn, who lived with Salter at the time of his death, identified a knife in court as belonging to Salter, bigger than the eight-inch wood-handled knife the St. Tammany Parish Sheriff's Office said was found at the crime scene.
Jurors also heard telephone recordings of Bierria seeking emergency help, telling a 911 dispatcher of an "altercation," the newspaper said.
Bierria played football at the University of Georgia, and two years with the Seattle Seahawks after being drafted in 2002. In 2005, he was imprisoned for selling narcotics, and apparently reconnected with Salter after his 2009 prison release, the newspaper said.
